IMPROVEMENT IN SHOVEL-PLOWS.

Specification forming part of Letters Patent No. 186,993, dated February6, 1877 application filed August 7, 1876. a

To all whom it may concern:

Be it known that I, THOMAS HENRY CLAY Dow, of Tampico. in the countyofWhitesides and State of Illinois, have invented a new and usefulImprovement in Shovel-Plow, of which the following is a specification:

Figure 1 is a side view of my improved plow. Fig. 2 is a rear view ofthe same.

Similar letters of reference indicate corresponding parts. v

The object of this invention is to furnish an improved shovel-plow,which shall be so constructed that'it may be adjusted for use as anordinary shovel-plow, or turned toward either side to form a right orleft hand plow, as the particular work to be done may require.

The invention consists in the plow-plate, the

right-angled bar, and the obtuse-angled bar,

constructed and combined with each other, as hereinafter fullydescribed.

A is the plow-plate, which is made diamondshaped in its general form,with its upper angle cut off, and the edge rounded off, as shown in Fig.2. B is a brace or supportingbar, which is bent at rightangles, so thatits upper arm may be vertical and its lower arm horizontal. Thehorizontal arm of the bar B, ,which serves as a foot for the plow, ismade with its lower side right-angled, as shown in Fig. 1, and itsforward end is beveled off, and is riveted to the lower angle of theplow-plate A. The end of the vertical arm of the bar B is riveted to theupper end of the plow-plate A. The lower part of the plow-plate A isconcaved and curved, and its side edges are curved forward, so that theyWill Wear sharp. The upper part of the plow-plate A is flat, and iscurved forward at a little greater curve than the lower part. 0 is abar, the lower part of which fits against the rear side of the verticalarm of the bar B, and is slotted to receive the bolt E, by which it issecured to said vertical arm, so that the plow can be adjusted higher orlower, as may be desired. The bar Ois bent at an obtuse augle,-and hasholes formed in it to receive the bolts E, by which it is secured to thestandard D.

By this construction, by loosening the bolt E, the plow-plate A may beturned down to the right or left, as may be desired, and by tighteningthe said bolt it will be held securely in the position into which it hasbeen adjusted.

Having thus described my invention, I claim as new and desire to secureby Letters Patent The plow-plate A, the right-angled bar B, and theobtuse-angled bar 0, constructed and combined with each other,substantially as herein shown and described.

THOMAS HENRY CLAY DOW.
